Answer:
15a
Step-by-step explanation:
To find the perimeter, add up all the sides lengths
3a+4a+8a
15a
The perimeter is 15a
The interest is $58,760.84
The total is $133,760.84
2(4-16) - (-30)
= 2(-12) -(-30)
= 24 - (-30) ....Error right here....a negative multiplies a positive = negative (= -24 + 30)
= 24 + 30
= 54
Correct:
2(4-16) - (-30)
= 2(-12) -(-30)
= -24 - (-30)
= -24 + 30
= 6
Answer:
B- 125
Step-by-step explanation:
c + a = 400
a = 400 - c
5c + 8a = 2825
5c + 8(400 - c) = 2825
5c + 3200 - 8c = 2825
3c = 375
c = 125
(6/13)/(6/12)= (6/13)*(12/6)= 12/13
This rule for division applies to all fraction divisions
